A person should consider seeing a dermatologist if they develop cysts, nodules, or deep, painful acne, particularly when breakouts are severe or difficult to manage. Professional evaluation can help determine the underlying cause and reduce the risk of scarring.
Dermatological care may also be appropriate for late-onset or persistent acne. Late-onset acne develops in adulthood in someone who did not experience acne previously, while persistent acne refers to acne that continues or returns after adolescence. A dermatologist can recommend appropriate treatment based on the type and severity of the acne.
